Title: Forward tumbling prevention structure for desk
Inventor: YOKOO KENJI
IPC: A47B17/00
Filed: 1994-04-04
Abstract: PURPOSE:To obtain a forward tumbling prevention structure which achieves high workmanship with easier mounting and is hard to damage. CONSTITUTION:A shaft hole 40 is made to pierce a free end part of a shaft plate 38 formed at the center of a bumper 14 and a roller 44 is supported on the shaft hole 40. In this manner, the bumper 14 is integrated with the roller 44 to allow the prevention of forward tumbling of a desk simply by mounting the bumper 14 on the lower rim of a drawer. When the drawer is pulled oat, the front of the drawer is supported with the roller 44 rolling on a floor surface to allow the smoothing of the pull in/pull out operation. In addition, as the roller 44 is arranged inside the bumper 14, even when an obstacle hits a buffer plate 16 of the bumper 14, the impact energy is absorbed, not transmitted to the roller 44, eventually causing no damage to the roller 44. The roller 44 can be removed from the shaft plate 38 easily by pushing the shaft plate 38 to expand in the direction of separating from the roller.
